The BD9B300MUV-EVK-101 from Diodes Incorporated is an evaluation board used to demonstrate the functionality of the BD9B300MUV synchronous rectified buck converter. This isolated DC/DC converter is designed to provide up to 30W of power in presence of the 2:1 wide input voltage range, and its operating efficiency is up to 91%. The isolation voltage of the evaluation board is specified at 1,500VDC. This evaluation board requires an external digital isolator for transferring the control signals from the off-board controller to the board for controlling all of the parameters.

The application field of this BD9B300MUV-EVK-101 evaluation board is rather wide and covers a variety of industrial, automotive, and communication systems. It can be used for distributed power systems with input voltages up to 450V, industrial robotics and automation equipment, telecom / DC-DC power supplies, solar and renewable energy inverters, as well as portable medical and automotive applications. In combination with an external controller and a digital isolator, the evaluation board can be used for a reliable and efficient power management.

The BD9B300MUV-EVK-101 evaluation board is designed to be very easy-to-use and to support variety of configurations. The board allows quick and easy evaluation of the BD9B300MUV synchronous rectified buck converter and provides adjustable features such as adjustable output regulation set point, ramp-rate control and under-voltage lockout. It also allows adjustment of the power converter\'s operating parameters, such as switching frequency, soft start time, and peak current. These adjustable options allow users to set the board to the desired outputs and verify the converter\'s behavior with minimum interference.

The working principle of the BD9B300MUV-EVK-101 evaluation board is based on the synchronous rectified buck topology, which combines low-RdsOn eFET drivers and synchronous rectifiers for improved efficiency and easy implementation of the Industry\'s latest high frequency switching. This topology also enables the device to achieve up to 91% efficiency. The board is designed to drive an external power Isolated Gate Bipolar Transistor (IGBT) on the primary side, which allows the device to achieve high levels of power density and efficiency.

The BD9B300MUV-EVK-101 evaluation board uses a Controller Area Network Serial Communication (CANS) link for programmatic control, and is compatible with a vast portfolio of Diodes’ controllers and digital isolators. In order to power up the board, the BD9B300MUV-EVK-101 requires an external input supply of 38V to 45V. This can be provided either through an external circuit or by using the on-board jumper. The two external feedback resistors are used to adjust the output regulation set point of the board, while the on-board soft-start capacitor is used for controlling the inrush current of the power converter.

The BD9B300MUV-EVK-101 evaluation board from Diodes Incorporated is an excellent choice for a wide range of applications, such as distributed power systems, industrial robotics and automation equipment, telecom / DC-DC power supplies, solar and renewable energy inverters, as well as portable medical and automotive applications. With its wide input voltage range, adjustable options, and compatibility with a vast portfolio of Diodes’ controllers and digital isolators, the BD9B300MUV-EVK-101 evaluation board offers a reliable and efficient solution for power management.
